How to make collision with foliage?

I made the forest with “foliage”. How can I make collision?

Hi Anilarion,

There are several How-to’s for creating Collision assets for your meshes here: Collision Tutorials in Unreal Engine | Unreal Engine 5.1 Documentation

Essentially you can use multiple basic collision hulls depending on the foliage in the Static Mesh Editor.

For instance, if you have a stree. You can use a single sphyl or box collision shape for the trunk and then if you have a more round top part of the tree you can use a basic sphere to have collision there.

Keeping the number of collision hulls and geometry as simple as possible is much better for performance than 100% accurate collision.

I hope this helps.

I just go to the static mesh edit it then to the collision tab do the simple box collision

Open your foliage static mesh and add collision (if it doesn’t already have it) using one of the options below:

You can then change the collision preset if you want to by going to the collision section of the details panel:

I did These but when i go back to the mesh the collisions specifically don’t save even if i click save
